> sort them by incredibly small amounts of manufacturing error and make those correspond with devices that have similar amounts of manufacturing error

I spent a little while unsuccessfuly trying to recall the jargon or the anecdotal company-name here, but IIRC there was an early pioneer in this where a company making radios (?) tried to develop a software system that would categorize non-conforming parts so that the flaws in different pieces would cancel out.

I don't think it worked for them, at the time it was far more efficient to just spend money on improving the quality and tolerances of the parts.
